The Zonai Fabric is a key item from Tears of the Kingdom.
Tears of the Kingdom
"Tough fabric bearing a Zonai design. It looks like it could be used to make a paraglider."
On a visit to Great Sky Island, Link sees a column of light on top of the Temple of Time's roof. At the base, he finds a Steward Construct who challenges him to light three bonfires around the island between two chimes of the time bell without setting foot on the ground outside the temple roof. When Link succeeds, it tells him the story of how Great Sky Island came to be, and gives him the Zonai Fabric as a token of his success.
